Good service, on time, very professional

Sigma Air conditioning came out to fix our wall air conditioner/heater. We were very happy with the service we received – shows on time, courteous, and most importantly fixed our Ac/heater for a reasonable price. We would definitely use Sigma air again

Very Professional

I have used Sigma Air Conditioning for many years . In fact, they installed my current unit many years ago and have been maintaining it ever since. They are an excellent, family-owned and operated company. I’ve recommended them to all my friends who need a good, reliable company.

Highly Recommend

I’ve used Sigma twice – once last year to do an AC tune up at a newly purchased Condo in Manhattan and again recently to repair an Islandaire PTAC AC unit at my rental property. is fast, efficient, honest, and skilled. I have used other AC contractors in the past with mixed results. I have had nothing but good results with Sigma Air Conditioning, Highly recommend.

Ice Air installation

sigma air conditioning installed two ice air PTAC units in my apartment in NYC. Everything that was delivered, from the estimate to the installation was very professionally done.They were very professional and got the job done right in a timely manner. All the work was done at a fair price that was much lower than two other high-rated companies that gave bids. I highly recommend this company.
